Fix contact form crash, analytics range filter, Scripture Index parsing, and unsafe-delete UI bugs

- server/routes/contact.js: import fireWebhooks (was undefined, throwing on every submission)
- server/routes/analytics.js: filter admin-stats by row.at, the field recordVisitor actually sets, instead of the never-populated row.visitedAt
- src/App.tsx: parseSIRef now supports chapter-spanning verse ranges (e.g. "5:15-6:2"); SI_BOOK_MAP indexes both spaced and unspaced book names so multi-word Bible Book values from the admin field resolve correctly
- src/App.css / src/App.tsx: fix Episodes/Studies nav dropdown menus being unclickable — a positioning gap between the trigger and menu created a hover dead zone; menu is now flush with spacing moved into padding so hover carries through
- src/components/StudySectionComments.tsx: check response status before removing a comment locally, so a rejected delete no longer appears to succeed
- src/components/QASection.tsx: don't bail out of search scoring for 1-2 character queries, so short substrings like "OT" or "AI" can still match
- src/AdminPage.tsx: check response status in study-user, QR code, and episode-script delete handlers before updating local state
